The expansion of power transmission systems is an important part of the expansion of power systems that requires enormous investment costs. Since the construction of new transmission lines is very expensive, it is necessary to choose the most efficient expansion plan that ensures system security with a minimal number of new lines. In this paper, the role of Flexible AC Transmission System (FACTS) devices in the effective operation and expansion planning of transmission systems is examined.

The most vexing problem plaguing Rumuomoi's 11kV distribution network is voltage sag and swell, which degrades power quality. There has been no effective mitigation control implemented. The purpose of this research is to address the issue of power quality by implementing artificial neural network (ANN) control with an embedded dynamic voltage restorer (DVR). To begin, the artificial neural network is trained using the input and desired data obtained during simulation using a proportional integral (PI) controller. To limit the amount of data obtained during training, the Levenberg-Marquardt fee

Abstract This paper proposed a method to investigate the effect of increasing PV penetration on the voltage stability of an IEEE 14-bus test system considering maximum PV penetration and system loadability limit. The critical bus of the test system has been decided based on nose curve analysis. The solar PV system is deployed with the most critical bus of the system. The effect of increasing PV penetration on the improvement in the loading capacity of various power system components like transmission lines, transmission line transformers, and generators is investigated over the adopted test sy

Reasonable allocation reactive power compensation devices in coal mine system can not only develop power factor, it can also solve bus voltage fluctuation problem of coal mine system. By analyzing load characteristic in coal mine system, non-linear impulse load and induction motor can cause bus voltage fluctuation. The characteristic of SVC is that its response speed is quick and it can be adjusted continuously. But the price of SVC is expensive. Reasonable allocation method is that a portion SVC is installed in the bus that are connected with a number of non-linear impulse load and induction

Usually, the concept of full weighted least square state estimator is a nonlinear technique, but with conventional process and PMUs it may improves the accuracy of the measurement without doing a bulky iteration procedure. In this paper the way of formation of measurement by using Full weighted least square state estimation and PMU device with conventional method will be investigated. A number of cases are te

The quantity and frequency of disruptive events have increased significantly, which might have obvious adverse impacts. A large number of passengers are stranded at disrupted URT station when a disruptive event occurs. One essential solution for passenger evacuation is the bus bridging service. This paper is aimed at addressing the passenger evacuation problem caused by a disruptive event in the URT network, by proposing a bus bridging service model considering the passengers
